As will heseon, said rib extends to the outer edge of the rim part 1 and to the inner edge of the hub par and is oi double the thickness oi? the main portion of the plate, tl'iorehy seouiiiiig greur strength and permi ting the spoke part of the rib to he tzrpera m indimted in I 2, from fihe hub towards the rim.

The hub shell. as shown may consist of the horizontal part slotted from one edge and the vertical par; which is embraced or engaged by one of he hub flanges and rests upon the hub barrel 11.

In the modification of my invention illustrated in Figs. i and 5, sector-shaped metal plates may be used each having rim, hub

and spoke part all integral with one another and each sector-shaped plate may be bent up on the lines 77 to form a radially extending flange 8 disposed transversely to the general plane of the plate. Said sectors being assembled and built up to form the complete wheel, the flanges 8 of contiguous sectors will lie against one another and will form in effect strengthening ribs of double thickness. Said flanges of the contiguous plates may be fastened together, if desired, by spot welding or otherwise. In this form of my invention folding or bending on the lines 6-6 dispensed with.

12 indicates the outer rim which has preferably the inwardly turned flange as indieated and which receives and which may be secured to the rim part. 1 in any desired way.

lVhat I claim as my invention is l. A metal wheel having a rim, hub and spoke part integral and consisting of a plate or sheet of metal provided with radial strengthening ribs integral with the plate and formed of a portion thereof bent transversely to the plane of said plate, said ribs extending through the spoke parts into the rim and hub parts.

2. A metal wheel having rim and hub parts both circumferentially continuous and integral with the spoke parts, all formed of a single plate or sheet of metal bent or folded in a radial line of the spokes to atford radial reinforcing ribs extending eon tinuously through the spoke parts and the rim parts to the edge of the plate. the plane;

of each rib disposed transversely to the plane of the wheel.

3. A metal wheel having a continuous rim, :1 continuous hub and individual spokes integral ,with one another and consisting of a single plate or sheet of metal, said individual spokes having strengthening ribs con- 5. A metal wheel embodying a metal plate constituting a rim part, a hub pa rt and a spoke part of the wheel and prox'ided with a strengthening rib integral with the plate and formed of a bent portion thereof bent transversely to the plane of the plate and the plane of the wheel and embracing the hub, rim and spoke portions of said plate.

6. A metal wheel having spoke parts integral with rim and hub parts and all formed of a sheet metal plate, said spoke parts having radially extending reinforcements formed of a double thickness of the sheet metal and integral with the plate.

7 A metal wheel having a circumferentially continuous rim and hub part and a spoke part all integral with one another and consisting of a single plate of metal, said wheel having radial strengthening ribs also integral with the plate.

8. A metal wheel having a spoke part integral with circumferentially continuous rim and hub parts all formed from a sheet metal plate and provided with radial reinfol-cements formed of a double thickness of the sheet metal and integral with the plate.
